SNOWPLOW.

Application led October 3, 1924. Serial No. 741,378.

To all 107mm 'it may concern:

Be it known that JOHN EADY, a citizen of the United States, residing at Fifeliake', in the county of Grand rllraverse and State of Michigan, has invented certain new and useful Improvements in Snowplows, of which the following is a speciiication.

This invention relates to snow plows generally and particularly to plows for removing snow from railway tracks and among the various objects thereof may be mentioned the following as prominent ones:

To provide a snow plow for railways' with means for vertically adjusting the forward receiving end thereof with relation to the ground or snow surface; j

To provide a snow plow with a forwardly and downwardly inclined body with side boards adjustable for the purpose of' de.

livering snow onto a flat-ear in the rear of and coupled therewith or for delivering the snow to the sides of the trackway;

To provide novel and simple means fori` operating, adjusting and supporting the mechanisms and elements for carrying out these objects.

With these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.-

Referring to the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention,-

Figure 1 is a side elevation of the snow plow; f

Figure 2 is a substantially central. longitudinal section; y

Figure 8 is a plan view showing alternative position of the side boards; l

Figure 4 is a bottom plan view of the machine;

Figure 5 is a transverse section on the line 55 of Figure l;

Figure 6 is an enlarged detail bottom. plan view of the stanchion locking means; and

Figure 7 is an enlarged detail section thereof.

Referring specifically to the drawings by numerals of reference, 2 designates a railway track and 4, in dotted outline a flat-car to which my snow plow may be coupled. as a one source of propulsion. Y, V

The sto-'w forming the subject or this invention comprises a forwardly and downwardly inclined frame 5, the side and end sills of which are shown respectively at 6 and 8, said frame supporting the body 1() in the usual or anyv approved manner. 60 The frame 5 is supported to the rear of its longitudinal center by means of pairs of standards 12 and 14, the former beingrelatively shorter than the latter and each being bolted to the under face of the side sills at their upper ends, while their lower ends which may be formed into a unitary structure as at 15 are bolted upon the upper face of journal blocks 16 in which is journaled the rear axle 18 carrying the track wheels' 19. To lend greater stability to the structure, I provide a pair of crossed struts ortie bars20 connected at their ends respectively witlfthe under face of the side sills and the journal blocks 16. Supported at its ends respectively in the forward transverse sill 8 and a hanger 21 depending from and supported by the rear portions of the side sills 6, is a centrally and longitudinally disposed kdraft or pusher bar, 22, the rear extremityl being provided with a coupler 24 for connection to the draw bar 25 of the flat-car 4.

In practice,'the rear delivery end of the plow body is disposed over the adjacent B end of 'the liat-car as shown in Figure 1, and as the snow is gathered by the knifeedged forward extension 26 of the metal floor, it is moved upwardly and rearwardly between the side boards 28 and eventually deposited upon the flat-car. Under certain conditions it is desirous tha the' snow be delivered to the sides of the at 29 in any suitable manner, whereby lsaid side board may be swung inwardly as shown by dotted lines in Figure 3 so that they present in plan, a i/ or triangle the apex or eut- 'ting point 30 of which is forwardly directed to causethe snow gathered by the forward extension to be moved laterally and ofi the side of the car.

To provide means for maintaining the side boards 28 in either of the positions described or as shown respectively in full and dotted lines in Figure 3, there are arranged in pairs upon the opposite sides of the car and adjacent the center'l respectively, stanehions 32 with locking devices forsupporting them in lined position, and since' the stanchions' and,

the locking uneans `inc-ident tto leach are :of thesameconstruction, only one Lneedbe described. Y

Each stanchion 32 coni-prises ainetallie-bar Aand proyidedl with an `opening,` 'registering lwiththatinfthe ear i'loorls acastlng,- 36

provided with an annular `lange S38, the latter "having an arcuate slotf). FArranged to oseillate ina horizontal plane within the annular lange 38, is a locking plate or disjlr 40, having` a central bayonet opening leilin registry-with'the-openings 34 andf in the ear floor and castingrespeetively, saidfdisk Ybeing nprovided with a radial operating'arin which is inovable in the arcuate slot It is Aobvious trom reference to Figures vand 7 that when thestanchion has its lower ,end Vprojected through the several yregistoring openings 3d, 35 and del, yand `the dislr() turned through an angle o ,QOldegreea the lugs 4,3 `willtake under `the lower *aceof the said disk and loethus lockedlagainstreinoval. i

' Under'certain conditions, as `for instance .in 'transporting the plow from place to place, or Awhere it is `desired to regifl'late ythe vertical l' eleiation of the `forward end `therefof, it is necessary 'to provide means for eiectlng the raising or lowering ot said forward end,7 and for this purpose, l journal the forward axle in thelower .ends ofthe arms lO o an inverted VAU-shaped llink or standard, the horizontal transverse member 5l `of which passes through Aand 'is suitably journaled in the forward `portions offthe side sills 6. The vertical adjustment is aifected by swinging the link :and with it, `the `front wheels 66 on `the Yaxis of ithe "transverse bar 5l, `andto this end, )l provide an lactuating' rod 5l, -the lforward bifurcated ends of which are provided with eyes through which passes Lthe front axle 118, while therear end is Vpivotally,connected asl at 56-with the crank arin 59` of a crank shaft GO,journaled transverselybelow the floor of the car body vinthe standards 14. The crankV shaftmay'beoperated eitherby a handle inent 4ofy pulley 4may be 4*used to reverse the opera-tion ofthe Crank shalt 60.

iF-rom the foregoing description o' the construction of lnay linigroifed apparatus, it `will lbe seen that 'il hare provided a simple, inexpensiveand elflic'ient means for carrying,` out the objects of the invention, and `while l have particularly described lthe elements best adapted to vperform the lfunctions set forth, itis obvious that various ychanges in forni, proportion, land in fthe minor details of construction may be resrted to, without dep arting from the `spirit A or sacrilioin Aany ,of Athe principles of the invention.
